使用XSLT修改会导致xslt停止工作

Question

我有一个XSLT样式表，看起来基本上就像：

<?xml version="1.0" encoding="utf-8" ?>
<!--

    <xsl:template match="value[@name = 'field_name' or @name = 'field_type' or @name = 'field_dim']" mode="values">

更新：   - 任何记录都应包含1个Value节点，其中包含所有字段。因此，将xsl：element应用于模板会将每个单独的字段放入其自己的Value节点，这在当前情况下是“坏的”。问题仍然没有以这种方式发展，即这些记录可以嵌套在彼此内部，每条记录应该只包含一个具有所有类似字段记录的Value节点。

我的第一印象是修改XSLT脚本以创建xsl：元素，因为您可以在上面的XSLT中看到注释，但是这会导致每个记录字段的Value节点，这将假定包含的记录有1字段，实际上是数组。

她的样式表基于你的一些变化。
 正如我之前所说：如果Record元素应该嵌套在Value元素中，则需要在xsl:apply-templates内使用<xsl:element name="Value">。

请试试这个：

          <Value>{NS}</Value>
        </record>
        <record path="sig_out/formatted_email/recv_date">
          <Name>recv_date</Name>
          <Type>string</Type>
          <Depth>SIMPLE</Depth>
          <Value>{NS}</Value>
        </record>
        <record path="sig_out/formatted_email/body">
          <Name>body</Name>
          <Type>string</Type>
          <Depth>SIMPLE</Depth>
          <Value>{NS}</Value>
        </record>
      </Value>
    </record>
  </Outputs>
</Values>

您需要考虑的是以下代码中的值内容的条件：

<xsl:element name="Value">
    <xsl:if test="not(descendant::record[value[@name = 'field_name']])">
        <xsl:text>{NS}</xsl:text> 
    </xsl:if>
    <xsl:apply-templates >
        <xsl:with-param name="path" select="$path" />
    </xsl:apply-templates>
</xsl:element>

如果没有更多带有属性name = field_name的am值的记录，则会生成“{NS}”。否则就会生成记录。
